- All Implemented Interfaces:
- Application
- public class MultiWindowGraphEditor
- extends MultiWindowApplication
A graph editor for non-hierarchical graphs. This is a complete
graph-editing application that includes automatic layout, load from
and save to XML, editable properties, and so on. It is intended as
an example application that you can use to understand the
functionality of the diva.gui application framework, as well as a
basis for building a customized graph editor for your own
application.
This class subclasses diva.gui.MDIApplication. As such, it
implements a straight-forward one-to-one mapping from documents
to views. (If you need more complex document-view mappings,
you will need to subclass AbstractApplication and implement the mappings
yourself.) Subclasses of MDIApplication need to call setAppContext()
with an instance of MDIFrame (in this case, we use DesktopContext). They
also need to implement at least these methods:
- public JComponent createView(Document d)
Given an implementation of diva.gui.Document, create a suitable
widget and return it. The MDIApplication superclass will take care
adding it to the MDIFrame.
- public String getTitle ()
Return the title of the application -- this is shown in the
title bar of the AppContext and other places.
- public void redisplay (Document d, JComponent c);
Redisplay the document after it is mapped to the screen.
This only needs to be implemented by applications that need to
know the size of the component to draw properly (for example,
graph layout).
In addition to implementing diva.gui.Application, the only other
interface that must be implemented to produce a complete
function application is diva.gui.Document. See the CanvasDocument
class.
Please also read the method documentation for this class, as well
as the source code. Apart from providing implementation of the
methods described above, it also initializes menubars, toolbars,
and creates the Action objects that are executed in response to
toolbar and menu commands.

MultiWindowGraphEditor
public MultiWindowGraphEditor(DesktopContext context)
- Construct a new graph editing application. The application
will not have any open graph documents, until they are opened
by getting the "Open" action an invoking its actionPerformed()
method.
createView
public View createView(Document d)
- Create a view on the given document.
- Overrides:
createView in class MultiWindowApplication
getTitle
public java.lang.String getTitle()
- Get the title of this application
- Overrides:
getTitle in class AbstractApplication
initializePalette
public void initializePalette()
- Initialize the palette in the.
initializeMenuBar
public void initializeMenuBar(javax.swing.JMenuBar mb)
- Initialize the given menubar. Currently, all strings are
hard-wired, but maybe we should be getting them out of the
ApplicationResources.
initializeToolBar
public void initializeToolBar(javax.swing.JToolBar tb)
- Initialize the given toolbar. Image icons will be obtained
from the ApplicationResources object and added to the
actions. Note that the image icons are not added to the actions
-- if we did that, the icons would appear in the menus, which I
suppose is a neat trick but completely useless.
main
public static void main(java.lang.String[] argv)
- Create and run a new graph application
